With heating costs going through the roof, here’s an
easy way to keep heat from slipping out your doors,
too. Take 30 minutes and replace the weather stripping and
door sweeps around your steel entry doors. Plan to do this project on a
warm day since you’ll have to remove the doors. Steel doors
use a compression-style strip for the hinge side and a magnetic
one for the knob side and the top. But look at the door
and confirm the style of weather stripping on all three sides
and the type of door sweep before you head to the store.
You’ll find replacement weather stripping in a variety of lengths and colors at
home centers and hardware stores.
To remove the door, close it and use a hammer and a pin
punch or a thin nail to tap out the door hinge pins. Turn the knob, open the door slightly and lift it off the hinges. When
you rip out the old weather stripping, you might find that
it’s tacked into place with small brads from the manufacturer.
Leave them in place after removing the old weather
stripping or you’ll damage the doorjamb. Then shear off the
shanks inside the groove with an old chisel (Photo 2) or drive
them deeper into the groove with a screwdriver. Press the
new magnetic weather stripping firmly into the groove on
the knob side and top of the door frame and do the same
with the compression strip along the hinge side. To ensure
that the strips won’t pull out, pin them with a few 1-in.
brads, especially in the magnetic strips (Photo 3).
The sweep on the door bottom is even easier to replace.
Pry or slide out the old sweep. Run a bead of caulk along the
bottom edge of the door, tap the sweep into place and then
staple it at the ends (Photo 4). While you’re at it, you might
as well do a quick fine-tune of the adjustable threshold.
Adjust all four screws until the door opens and closes without
too much drag and any drafts have been eliminated
(look for light between the sweep and the threshold with
the door closed). Turn the screws clockwise to lower the
threshold and counterclockwise to raise it (Photo 5).
